Yes you are correct.Its not just about the closure of air flow but also the addition of fuel into the carburetor. This happens by the process where when we pull the choke ,The butterfly valve closes the air flow which makes the pressure difference inside the carbuteror and this leads to sucking of more fuel into the carburetor .So in this process we get a air fuel mixture rich with fuel to overcome coldstarting.lalSo, when we use choke, just the air flow reduces? Or will there be any increase in the fuel inflow too?

The answer is simple.If we use choke after you get a good start , It Will lead to high fuel consumption because when we pull the choke after start, a high air fuel mixture rich in fuel Will enter into engines via inlet valve from carburetor.As a result there is a high fuel consumption .So it is better to avoid choke after a good start.Anand TamariyaA related question would be - why should choke not be used for normal functioning after engine start?

Well the choke is only used when required because the normal use of furl is easily available by the fuel tank. But the case comes when the vehicle doesn't comes up with normal fuel available. That's why choke is used to provide more than required fuel to the engine that make it to start well.Anand TamariyaA related question would be - why should choke not be used for normal functioning after engine start?
